HORIZONTAL DISPLACEMENT PELVIC FRACTURES: TEN-YEAR ANALYSIS OF CLINICAL OUTCOMES AND TREATMENT STRATEGIES

Abstract

The purpose of the study was to describe a horizontal shear fracture of the pelvis. Data from 1,242 patients with pelvic and acetabular fractures were studied over a 10-year period (December 2008 to December 2018) at a level 1 trauma center. Of these, six patients (0.5% of the total) had horizontal shear fractures. Demographic, clinical, and radiologic data were analyzed, including pain, level of mobility, sciatic nerve symptoms, acetabular or pelvic surgery, and radiographic findings. Among the findings, it was noted that pelvic shear fractures are often caused by motorcycle accidents but are not fatal. Some patients required treatment for pain, mobility limitations, or total hip arthroplasty due to complications such as osteonecrosis of the femoral head. However, no fracture displacement or implant migration was observed. The overall assessment of post-traumatic arthritis was good or excellent, except for one case. The average follow-up duration was 1.8 years. In conclusion, it is noted that a horizontal shear fracture of the pelvis is a serious injury that requires open reduction and internal fixation to achieve good results.
